Description

Cooper Alloy Tube B111 C68700 O61 Annealed, Aluminium Brass Seamless Tubing For Sea Water Heat Exchanger

Short Introduction: C68700 Copper Alloy Seamless Tube

C68700 Copper Alloy Seamless Tube, also known as Aluminium Brass Tube, is a high-performance, non-ferrous tubing material made primarily of copper, zinc, and aluminium. It offers excellent corrosion resistance, particularly in seawater and marine environments, and is commonly used in heat exchangers, condensers, and power plant cooling systems.

The seamless design ensures leak-free operation under pressure and thermal stress. Its high thermal conductivity, good mechanical strength, and resistance to biofouling make it ideal for demanding industrial and marine applications.
